U2 frontman Bono agreed to do a television interview and concert in the Bosnian capital Sarajevo in 1997 to help the city's war ravaged people, despite knowing it would put him and his bandmates in danger.
The ONE singer made the decision after an emotional plea from US filmmaker BILL CARTER, who felt U2's visit would create good publicity and for the city which was, at that time, under siege from Serbian forces.
Bono, in an extract from the band's self named book, says, "Right on the edge of Europe there was a symbol of tolerance, where three ethnic groups - Croats, Serbs and Bosnians - lived together in peace.
"And this tolerance was being challenged by an appalling siege by Serbian forces.
"So I agreed in an emotional moment to do a gig there. And after I've agreed on Sarajevo Television, I then have to explain to the band why putting our lives at risk is going to help the people of Sarajevo."
Bono's decision was not met with approval by all his band members, particularly drummer Larry Mullen Jr, who felt the plan was immoral.
U2's manager, PAUL MCGUINNESS, says, "Larry was pretty much against it. He thought we were exploiting people's misery for entertainment.
"Bono definitely felt that we were shining a light on something important."
